    摘要: A base station transmits control information to a mobile station. A first control channel is transmitted to the mobile station. The first control channel contains an indication of the number of control channel occurrences in a frame. A second control channel is transmitted to the mobile station in a control subframe. The second control channel contains information for communicating a packet between the base station and the mobile station. The control subframe is determined from the number of control channel occurrences in the frame. The packet can then be communicated between the base station and the mobile station in a subframe based on the control channels transmitted.

    摘要: A system and method for relaying transmissions in wireless communications is provided. A method for combined relay node operation includes determining an operating mode of the combined relay node, where the combined relay node includes a repeater and a relay. The method also includes if the operating mode is repeater on mode, amplifying and forwarding received signals, and storing subframes, where subframes are demodulated and decoded versions of the received signals. The method further includes if the operating mode is repeater off mode, amplifying and forwarding a control zone of signals received while the operating mode is repeater off mode, and transmitting subframes stored while the operating mode is repeater on mode.

    摘要: In the system acquisition process system information is non-coherently detected using correlation of reconstructed and received preamble signals, such as the primary broadcast control channel (PBCCH) and the acquisition pilots (TDM1, TDM2, and TDM3). The phase correlation signals between the correlated signals of PBCCH and TDM2 or TDM3 and between the correlated signals of TDM2 and TDM3 are combined to decode other sector interference (OSI) information and the like. Acquisition is also made more efficient by taking advantage of predictable information based on system synchronicity. The sync/async bit is included in at least one of the acquisition pilots. The mobile then uses knowledge of system synchronicity to more efficiently detect the additional information in the superframe preamble.

    摘要: A system and method for transmitting and receiving control information over a control channel of a wireless communication system where the conveyed information is coded and then transformed by a set of transform function selected from a plurality of sets of transform functions. The control information is transmitted as replicated sub-frames containing replicated code words and such a string of transformed replicated code words is referred to as a control message. At a receive end inverse transform functions from different sets of functions are applied to a sub-frame of a control message so that if the sub-frame is successfully decoded the inverse transform function applied to such frame allows the timing of the control message to be determined.
